A THREE-DIMENSIONAL AEROSOL VARIATIONAL DATA ASSIMILATION SYSTEM FOR AIRCRAFT AND SURFACE OBSERVATIONS
Data assimilation WRF/Chem Aerosol Aircraft
2018/5/16
A three-dimensional variational data assimilation system is implemented within the Weather Research and Forecasting/Chemistry model, and the control variables consist of eight species of the Model for...
Hydrological Modelling and data assimilation of Satellite Snow Cover Area using a Land Surface Model,VIC
Snowmelt Runoff Beas VIC model MODIS SCA Data Assimilation Direct Insertion Ensemble kalman filter (EnKF)
2016/11/30
The snow cover plays an important role in Himalayan region as it contributes a useful amount to the river discharge. So, besides estimating rainfall runoff, proper assessment of snowmelt runoff for ef...
STUDY ON ENVISAT ASAR DATA ASSIMILATION IN RICE GROWTH MODEL FOR YIELD ESTIMATION
Rice Yield Map Crop Model Radar Model Data Assimilation Optimization Algorithm Classification
2015/12/28
In this paper, a practical scheme for assimilation of multi-temporal and multi-polarization ENVISAT ASAR data in rice crop model to map rice yield has been presented. To achieve this, rice distributio...
CROP MODEL DATA ASSIMILATION WITH THE ENSEMBLE KALMAN FILTER FOR IMPROVING REGIONAL CROP YIELD FORECASTS
Crop model data assimilation Ensemble Kalman filter
2015/9/8
Uncertainty in spatial and temporal distribution of rainfall in regional crop yield
simulations comprises a major fraction of the error on crop model simulation results. In
this paper we used an Ens...
A FRAMEWORK OF A REMOTE SENSING DATA ASSIMILATION SYSTEM
Estimating environmental variables satellite observation
2015/9/8
Estimating environmental variables from satellite observation is often an ill-posed
inversion problem. There are currently multiple satellite sensors available for monitoring
land surface environmen...
Global sensitivity analysis,probabilistic calibration,and predictive assessment for the data assimilation linked ecosystem carbon model
Global sensitivity analysis probabilistic calibration predictive assessment data assimilation linked ecosystem carbon model
2015/8/6
In this paper we propose a probabilistic framework for an uncertainty quantification (UQ) study of a carbon cycle model and focus on the comparison between steady-state and transient simulation setups...
Data assimilation is the process of combining our knowledge of a system, including both observations and dynamics, to produce estimates of the state of a system. The state of a system, or state variab...
The modular ocean data assimilation system (MODAS) was designed to meet the U.S. Navy's need to produce rapid estimates of present and near-term ocean conditions, often in situations where little or n...

Ocean Research Progress and Prospects
2015/7/23
This report summarizes goals, activities, and recommendations of a workshop on data assimilation held in Williamsburg, Virginia on September 9–11, 2003, and sponsored by the U.S. Office of Naval Resea...
Eastern US Continental Shelf Carbon Budget:Integrating Models,Data Assimilation,and Analysis
Eastern US Continental Shelf Carbon Budget Integrating Models Data Assimilation Analysis
2015/7/20
The past two decades have seen the development of large multidisciplinary oceanographic programs that focus on understanding carbon cycling processes in coastal and oceanic environments. Synthesis and...
A Forecasting Procedure for Plate Boundary Earthquakes Based on Sequential Data Assimilation
Plate Boundary Earthquakes Sequential Data Assimilation
2015/7/17
A forecasting procedure is proposed for plate boundary earthquakes in subduction zones. It is based on spatio-temporal variation in slip velocity on the plate interface, which causes interplate earthq...

Integrating Biogeochemistry Ecology Ocean Data Assimilation Systems
2015/7/6
Monitoring and predicting the biogeochemical state of the ocean and marine ecosystems is an important application of operational oceanography that needs to be expanded. The accurate depiction of the o...
GODAE: The Global Ocean Data Assimilation Experiment
GODAE Global Ocean Data Assimilation Experiment
2015/7/6
During 1996 and 1997, Neville Smith and Michel Lefèbvre developed the Global Ocean Data Assimilation Experiment (GODAE) concept (Smith and Lefèbvre, 1997). Its central idea was to conduct a 10-year in...
Ocean data assimilation has matured to the point that observations are now routinely combined with model forecasts to produce a variety of ocean products. Approaches to ocean data assimilation vary wi...
The Impact of Multi-Sensor Data Assimilation on Plant Parameter Retrieval and Yield Estimation for Sugar Beet
yield modelling crop growth model PROMET
2015/5/6
Yield Maps are a basic information source for site-specific farming. For sugar beet they are not available as in-situ measurements. This gap of information can be filled with Earth Observation (EO) ...
